alarms are disabled and all interlocks are defeated.
2.2.3 Field Calibration
The purpose of calibration is to ensure the accuracy of the airflow display and alarm (if present). This involves
measuring airflow with reference instrumentation and establishing reference between airflow sensor(s) on the
BSC to the standard reference. Calibration should only be carried out by trained personnel. This section
presents a brief overview of the calibration menu function. For more information, refer to test report.

This option allows the user to reset all value calibrated in the field and return it to the values gathered in
factory calibration.
2.2.4 Admin Settings
The admin menu allows you to change both FAN and ADMIN PIN. The reset blower, filter and UV hour meter
functions are usually used after you change the blower, filter or UV lamp as they can easily give you the
indication on when to do BSC maintenance. While the reset default function will return the options in the
settings menu to their factory settings.
2.2.4.1 New ADMIN PIN (default 0009)
ADMIN PIN restricts access to some of the more delicate menu functions, namely admin and field calibration,

2.2.4.2 New FAN PIN (default 0000 - DISABLED)
FAN PIN restricts access to fan control and some parts of the menu, settings and set mode. User must enter
four-digit PIN before switching fan on or off. As such, it can restrict access to operating the BSC by
unauthorized personnel. It will also prevent unauthorized shutdown of the BSC when continuous operation is
required. Note that continuous operation is recommended for better safety. Fan PIN is also needed to disable
the alarm when the sash is fully raised and cleaning needs to be performed.
It is recommended that the Fan PIN be issued only to personnel authorized to use the BSC. With FAN PIN, the
user can access admin and set mode parts of the menu.
Setting the PIN to 0000 will disable this feature. The FAN PIN is disabled by default. When the FAN PIN is
disabled, the BSC can be turned on and off without requiring PIN, however to access the menu, the user is still
required to enter the FAN PIN (0000).

2.5 Alarms and Warnings
BSC uses alarms to indicate that the condition inside the BSC is not safe for the operator, so check the LCD
display to understand the cause of these alarms. The most common alarm is the SASH ALARM that indicates
that the sash is neither at the normal operating height nor at fully closed position (UV mode) – this condition
can easily be corrected by putting the sash at the appropriate operation position.
Other alarms that indicate a failure or an error in the BSC system:
AIRFLOW: NO! will be displayed if there is an airflow failure.
SASH:ERROR POSITION indicates a failure in the sash detection system.
SENSOR UNCALIBRATED will be displayed if the airflow velocity sensor is not yet calibrated.

3.1.2 Operating Motorized Sash Window (Only for BSC with motorized sash window)
The motorized sash uses a “push and hold” mechanism, so if you remove your finger from the button the sash
will stop immediately – this is a safety feature to control the closure and prevent anything getting trapped in
the aperture as the sash descends.
Lower Sash from Fully Open Position
When the sash is fully open, pressing the down button and holding it will cause the sash to move to the Safe
Height setting and stop. If the fluorescent lights are on as the sash descends, they will stay on as long as the
sash stops in the Safe Position (not applicable for NC2). If you release the button before the sash has reached
Safe Position the lights will switch off automatically.
Lower Sash from Safe Height Position
When the sash is at safe operating height pressing the down button and holding it will cause the sash to move
down to the fully closed position and stop. If the fluorescent lights are on as the sash descends, they will
switch off automatically as soon as the sash reaches fully closed. If you release the button before the sash has
reached the fully closed position the lights will switch off automatically
Raise Sash from Fully Closed Position
When the sash is fully closed, pressing the up button and holding it will prompt the user to input the password
to turn on the fan. If the password is correct, if it was on fan will turn on and the sash will move up to the Safe
Height setting and stop.
Raise Sash from Safe Height Position
When the sash is safe operation position, pressing the up button and holding it will cause the sash to move up
to the fully open position and stop. If the fluorescent lights are on as the sash rises, they will stay on as long as
the sash is allowed to fully open. Stopping the sash midway will cause the lights to switch off automatically.
Class II Biological Safety Cabinets
14
3.1.3 Using Sash Window
The sash window should be fully closed when the cabinet is not in use. This helps keep the work zone
interior clean.
The sash window should always be in the normal operating height at all times when the cabinet is in
use. Even if the cabinet is left unattended, but the blower is on, the sash window should never be
moved from the normal operating height, unless during loading or unloading of materials/apparatus
into the cabinet.
The alarm will be activated whenever the sash window is moved from the normal operating height.
Whenever the sash window is moved to the correct height from a higher or lower position, the light
will automatically be turned on as a signal to the user.
The sash window may be opened to its maximum position for the purpose of loading/unloading of
materials/apparatus into the cabinet. When the sash window is fully opened, the alarm sound may be
muted by pressing MUTE button but, will be automatically sounded again after 5 minutes to remind
the user that it is not safe to work in the cabinet and the light will be turned on to facilitate cleaning.
3.2 Starting and Shutting Down the BSC
3.2.1 Turning on the BSC
1.
Raise the sash to the indicated normal operational height (READY state). The lamp will turned on
when this height is reached.
Note: When Quickstart mode is selected, fan will turn on as well, without pressing the fan button.
2.
3.
Turn on the fan by pressing the FAN button. Input the Fan PIN if asked (if PIN ≠ 0000). This will start
the warm up procedure (default: 3 minutes). All buttons are diabled during warm up period.
The BSC is ready for work.
3.2.2 Turning off the BSC
1.
2.
Turn off the fan by pressing the FAN button. Input the Fan PIN if asked (if PIN ≠ 0000). This will start
the post purge procedure (default: 0 minute). All buttons are diabled during post purge period.
Lower the sash to the fully closed position (the display will show UV MODE). The sash can be lowered
immediately after turning off the fan as it will not interrupt the post purge procedure.
Note: When Quickstart mode is selected, fan will turn off without pressing the fan button.
3.
Turn on the UV lamp (when present) to decontaminate the work area by pressing the UV button.
Leave the UV lamp on to make sure the decontamination is done effectively . The UV lamp can
only be turned on after the post purge procedure is finished.
3.3 Working in the BSC
Surface-decontaminate the work area (work surface, back and side wall, UV lamp, electrical outlet,
service fixture and the inner surface of the sash window) before and after using the BSC.
Allow the BSC to purge any contaminant by allowing the blower to operate at least 3 minutes before
and after using the BSC.
Surface-decontaminate any item (including your arms) or apparatus with appropriate disinfectant
before entering or exiting the work area.
Place the waste container (containment bag, pippete discard pans, etc.) inside the BSC work area.
Place all items and apparatus in the safe working area.
Safe Working Area for Single Tray BSC
Safe Working Area for Multi Tray BSC
15
Minimize room activity (personnel movements, closing and opening of doors, etc.) since these
external airflow disturbances may adversely affect the BSC’s internal airflow, thereby possibly
impairing the containment capabilities of the BSC.
Ensure that the sash is at normal operating height (READY state) before starting any experiment.
Ensure the front and back air grilles are not obstructed by your arms or any other objects.
Work as far inside the BSC as possible - at least 150 mm (6 inches) behind the front air intake grille.
While working in the BSC, move your hands slowly and in a controlled manner. Rapid movements may
disrupt the air barrier, allowing contaminants to escape or enter the BSC.
The use of Bunsen burner inside the work zone is not recommended. However if the use of Bunsen
burner is unavoidable, place the burner in the right side of the work zone.
Place aerosol-generating instruments as far inside the BSC as possible and at least 150 mm (6 inches)
from clean items/materials.
Place air turbulence generating equipment such as centrifuges, blenders or sonicators towards the
back of the BSC. Stop other work while any of this equipment is in operation.
As far as possible, it is recommended that the BSC be operated continuously in order to achieve
optimal containment and cleanliness. Airflow studies have shown that once the fan has been
switched off, air from the BSC may escape due to the thermal currents from inside the BSC.
3.4 Working Ergonomics
On most occasions, you would most likely be operating the BSC in sitting rather than standing posture. There
are some obvious advantages of the sitting posture:
The physiological energy cost and fatigue involved in sitting are relatively less
Sitting posture provides the body with a stable support
However, sitting position has some drawbacks too:
The working area available is fairly limited
There is a potential risk of being constrained in the same posture for a long time
Sitting posture is one of the most stressful postures for one’s back
Therefore you should pay careful attention to the following guidelines in order to achieve comfortable and
healthy working conditions:
Always ensure that your legs have enough legroom.
Keep your lower back comfortably supported by your chair. Adjust the chair or use a pillow behind
your back whenever necessary.
You should place your feet flat on the floor or on a footrest. Don’t dangle your feet and compress
your thighs.
You should keep varying your sitting position throughout the day at regular intervals so that you are
never in the same posture for too long.
Observe the following precautions with respect to your eyes:
o Give your eyes frequent breaks. Periodically look away from the work area and focus at a
distant point.
o Keep your glasses clean.
Arrange the items/apparatus frequently used in your work in such a way that you can minimize the
physical strain involved in handling them.
Exercise regularly
The BSC’s noise emission has been tested and found to be in compliance with EN 12469, ISO 4871 and
NSF/ANSI 49 which is important to ensure health and comfort for the operator.
Ergonomics accessories available with Esco include:
Armrest padding
Lab chair
Footrest

3.5 UV Lamps
2
The UV light is a germicide and virucide. Even at the minimum acceptable irradiance in a BSC – 40 μW/cm (US
Department of Health and Human Services et. al., 2000), it would only take 12.5 minutes to reach 30,000
μW/cm2 (1 W = 1 J/sec), which has been listed as germicidal for spore forming organism.
Unlike many other type of decontamination agent, UV light doesn’t leave any residue. The decontamination
action stops upon de-energizing of the lamp.
However, due to the short wavelength, the UV light does not penetrate well. Thus UV light can only be used to
effectively disinfect the work area of an empty BSC. For any container stored inside the BSC’s work area, the
UV radiation will only disinfect the outer surface of the material, leaving the inner surface and the content
inside the material untouched.
UV light decontamination method may be used before and after working with vegetative organisms
and viruses. However, it should not be the sole decontamination agent; the use of chemical
decontamination agent is still encouraged.
Minimize the material inside the BSC’s work area during the process of UV light decontamination. A
direct interaction with UV light can degenerate plastic- or rubber-based material and can cause other
hazard.
Make sure that the BSC sash is in the fully closed position and the interlock is working properly before
activating the UV lamp. Avoid direct contact with skin and eyes as UV light is classified as a probable
human carcinogen.
The UV lamp should be activated for around 60 minutes to work effectively. Use the UV timer feature
to easily control the period of decontamination (UV timer is disabled by default). Leaving the UV lamp
on for over 60 minutes or even overnight is not recommended because it shortens the lifespan of the
lamp. The UV lamps used in Esco BSC have a lifespan of 2,000 hours.
The UV lamp should be cleaned of any dust and dirt weekly and changed annually to ensure its
effectiveness.
The use of UV lamp in BSC has been explicitly discouraged in all major international standards and
recommendations.
3.6 Decontamination and Disinfecting Agents
For stainless steel surfaces, all common disinfecting agents except chlorine-based ones are suitable.
For powder coated surfaces, all common disinfecting agents are suitable. However, the BSC has been
specifically evaluated for use with the following:
o 1N hydrochloric acid
o 1N sodium hydroxide
o 1% quaternary ammonium compound
o 5% formaldehyde
o 5,000 ppm hypochlorite
o 2% iodophor
o 5% phenol
o 70% ethyl alcohol
Depending on the contaminant involved at the time of operating the BSC, there are various other
types of disinfecting agents that may be used. The following table outlines the effectiveness of various
disinfecting agents against the different types of contaminants.

Decontamination
Decontamination may frequently be carried out by means of formaldehyde fumigation or using other
decontamination agents, such as chlorine dioxide or hydrogen peroxide. Decontamination process should only
be carried out by trained personnel.
In any of the following eventualities, the user should ensure that the BSC has been properly decontaminated,
keeping in mind the nature of the pathogens used:
At the time of moving/relocating the BSC
At the time of changing the type of work being carried out in the BSC
Before accessing contaminated areas for servicing, for example - filter replacement

Cleaning the BSC
Clean the work surface and walls with appropriate disinfectant agent and soap water afterward
Clean the sash window using an appropriate disinfectant agent and glass cleaner afterward
Use a damp cloth to clean the exterior surface of the BSC, particularly on the front and top in order to
remove dust that accumulated there
Use clean water to finish the cleaning and wash away any residue of disinfectant agent, soap water
and glass cleaner
For removing stubborn stains or spots on the stainless steel surface, make use of MEK (Methyl-EthylKetone). In such cases, make sure that you wash the steel surface immediately afterwards with clean
water and some liquid detergent. Use a polyurethane cloth or sponge for washing. Regularly cleaning
the stainless steel surface can help you retain the attractive factory finish.
Test the audible and visual alarm
The simplest method by far would be to move the sash until the glass window is no longer in the sash ready or
UV mode position.
Check the cabinet’s functionality
Check the BSC’s mechanical functionality; ex: sash window – lubricate if necessary
Check the BSC’s electrical functionality; ex: fluorescent lamp – replace if necessary
Check the BSC for any defect, repair immediately
Re-certification
All BSC must be re-certified annually by a certified engineer. See test report for recertification procedure.

Accessing the paper catch
The purpose of accessing the paper catch is to remove any retained materials that might cause obstructions.
Care must be taken as the area is contaminated.
Before opening the paper catch:
Use appropriate personal protective equipment (PPE).
Wipe down the interior of the BSC including the top and bottom surfaces of the work tray(s) while
airflow is operating.
If the interior cannot be wiped down, the BSC should be decontaminated
Accessing the paper catch
1. Turn the blower off. Then raise the sash to fully
open position for easy access.
2. Remove the tray(s) to access the paper catch.
3. The figure beside, points to the location of the
